CAPACITIVE PEN, CAPACITIVE TOUCH-CONTROL PANEL AND TOUCH-CONTROL DEVICE

摘要

Provided in the present disclosure is a capacitive pen for operating on a capacitive touch-control panel (200), comprising: a receiving unit (1) for receiving a measurement signal transmitted by the capacitive touch-control panel (200), a signal processing unit (5) for generating a high voltage signal synchronous with the measurement signal according to the signal received by the receiving unit (1), and a transmitting unit (2) for transmitting the high voltage signal to the capacitive touch-control panel (200) such that the capacitive touch-control panel (200) obtains the information of a capacitive pen (100). The capacitive pen of the present disclosure transmits a synchronous high voltage signal to enhance the sensing signal of a touch-control panel, such that the touch-control panel can sense a small-area conductor, thus expanding the function of the pen on the basis of finger touch control, and greatly improving user experience. In addition, the circuit is easy to realize, and has low cost and good compatibility.
